To all whom it may concern:

yBe it known that I, CHARLES H. CAsEBoLT,

a citizen of the United States, residing at Columbus ,Lowndes county, State ofMississippi 5 have invented certain new and useful Improvements in Processes of Delinting Cotton-Seed, of which the following is a specifi# cation.

My invention relates to certain new and 1:5 useful improvements in the process of extracting cotton-seed, and has especial-referenceto a process of separating and recovering linters from what is known as delint.

The object of my invention is to improve I5 what is known as delint 'by straightening it out and eliminating from 1t the dust and dirt and the extremely short ber, which is practically valueless. I accomplish this ob- ]ect as will be more fully hereinafter set zo forth in the drawings, specication, and

claims. A

In ginning cotton there is a considerable amount of hnt left on the seed when they come from the ordinary gins. If the seed are z 5 p passed directly to the cotton-seed-oil mill and are crushed and pressed, this amount of lint is wasted and that much of the. product is lost. It is therefore customary 11p-todate oil-mills to take thelseed as they come 3e to the mill and pass them through a modied type of gins, which gins are known tothe trade-as linters. The lint secured in' this way is baled and sold also under' the name of linters The seed passing through* the 3 5 linters go'to machines which grind off the remaining very short lint, which product is known as delint,l the machines used being known as delinters Nowinmy invention I have taken this roduct known as de- 4o lint and have carrie it back and have put it in with the Seed and with them passed it -into the machines known as the lintersf These machines with their rapidly-revolving saws whip out the very shortber, the dust,l 4 5 and motes and'straighten the other ber and l mixit with the llinters or cotton which they take direct-ly H the seed. They thus to a certain extent card this delint ber and to a very-large extent mix it with the linters, giy- 5o ing a product which is very sllghtly lower in grade than the best linters an yet which is to be hulled and crushed preparatory to largely increased in qualityand value over the delint which Went from the delinters to the linters. Y

In the drawings, Figure 1 is what is known 5 5 as a' flow plan of a cotton-gin or linter and delinter system and shows diagrammatically the path of the materials from the moment they enter the conveyers till they are nally discharged, with the names of the machines ordinarlly used written in. Fig. 2 is a dia-V grammatic view showing the conveyers and other apparatus necessary to carry out myl process.

1 is a conveyer which leads from the cotton-gins or seed-shed to the bell-reel 2 ,which separates out the .bolls and discharges them, as indicated, by the chute p 3. The seed passes from this reel directly by a conveyer and chute 4 to the sand-reel 5, the dirt being discharged, as shown, by the conveyer 6 'and the seed passing out, as shownby the arl row,jthrough a chute or conveyer 7 to the shaker S or other cleaning-machines, which removes additional dirt and other undesirable thinofs, discharging them through the chute 9, the seed passing over a magnet 8, through a conveyer 10, to the gins or linters 11. From the glins or linters 11 'the lint removed passes t rough a lint-Hue 12 to the condenser 12a and is baled. The seed asses through the conveyers 13 to the de= inters 14, -from which it is discharged into the conveyer 15, which carries .it to the hullers 8s pressing or to the storage-room or other re.- ceptacle. The usual procedure at present is to collect the delint removed by the delinters '14 and bale'it; but the delint so handled is dirty and full of extremely short lint, So that yit is of smallv value and commands an 'ex-I tremely low price., I have found, however, that by cleaning and to some extent carding and separating out the undesirable parts the quality is so much improved as to make the remainder of more value than the original larger quantity. In order to accomplish i this, I pass the delint removed by the delinters 14 into a conveyer 16, by which itis carried back to an elevator 16, bywhich it may be carried, as shown by the dotted extension 16", to the seed-conveyer 1 and passes, withA Vroo the seed, over and through A'the same ma-` chines, which are very eiiicient in removing the worthless particles. I have also` found that by passing the delint through the gins or linters that their-actionis to straighten the ber and eliminate short fiber and foreign matter and to thereby increase tlie value of the'product. It.` is also possible to accomplish this result by passing the delint'sepa'- a cially in Fig. 2, the delint from the delintersJ 14 would pass through the conveyer `16 t0 the chuteY 18, through which 'it wouldpass to a cleaner orl revolving screen 19, and thence directly to the conveyer 10 and as before described.

Referring lnow especially to Fig. v2, the

lboll-reel 2 consists of a hollow cylinder of wire-netting revolving about a shaft 21. The mixed bolls and seed are` discharged from the conveyer l into this reel, and as same revolves the seed drop through the netting, whereas the bolls, being too large to pass through, are carried to the end and are' dropped out intoy the chute 3. The seed whic pass through the netting drop into the conveyer 4 and attached chute, by. which lthey are carried to a lower reel 5, known as the sand-reel. This sand-reel is, like the boll-reel, a cylindrical reel of wire-netting, but of smaller mesh, the mesh being too small to permit the passage of the seed. This reel. is revolved and the dirt and sand sifted out through same into a conveyer 6, which carries it away, generally to the outside of the building. The seed pass out at the end of this reel and drop through a chute 7 onto an inclined table 8,known as a f shaker. This shaker is of the ordinary open-top type with `a screen for a bottom, and is reciprocated by a mechanism, (not shown,) so that it may shake out any sand or dirt remaining. The conveyers 1, 4, 6, 10, 13, and 15 are ordinarily screw conveyers, as shown byl the drawings. The linters 11 consist of a number of fine tooth-saws 22, arranged on an arbor 23, as in an ordinary gin, and passing between ribs 24, which are curved ordinarily as in the regular gins. 0H the saws by a revolving brush25 and from this brush is thrown, as shown Vby the arrow a, into the lint-flue 12, by which it is carried to a condenser 12a, which consists, primarily, of a cylindrical reel of wire-netting 26, mounted on a shaft 27 and rotating Itv is vmuch simpler,

The lint is brushed .slowly in the direction of the arrow. Lint in a fluffy state is thrown against this screen,

the dust and finer particles passing into the center of same and the cotton being formed intoa bat by means of a roller 28, which presses it against lthe screen 26. The con-v denser andvlinterfbeing of the ordinary type and in general use, no further description is,

believed to be necessary. y The delint-ers 14 may be of any ofthe numerous types now on the market; but for purposes of illustration ders of carborundum or like material 31,

which are rotated at a high rate of speed.-

Between these cylinders are corrugated slnelds 32,'which come close to, but do. not qulte touch, the said cylinders. The lint ground 0H by -the cylinders is blown through the space 33 thus left and drops out through the bottom of the casing 29. In the center of the casing formed by the cylinders and the pa'rtition 32 is a square shaft 34,` which has tangentially-pro'jecting blades 35, and which shaft is rotated rapidly in the opposite direction'from the cylinders 31. Cotton-seed is introduced at one end of the delinters through the spout 36 and drops `onto the plates 35, fastened to the rotating shaft 34, by which they are thrown violently against the partition 32 and the rapidly-revolving cylinders 31, and the delint (or very short lint) is ground 0H of them. The seed are gradually Apushed toward the opposite or front endI of the delinter by the pressure of the seed in the chute 36 and eventually pass out into a chute 37 at the front end of the machine, passing thence into the conveyer 15, by which they are'removed to the crushes. The lint passing out through the opening 33 drops down through the openbottom of the delinter on the belt conveyer 16, by which it is delivered to the elevator 16a and, as before described, is carried back and mixed with the seed as they go to the linters 11.

It will be distinctly understood that the essence of my invention lives in the process described and not in any particular ,mechanism by which this is accomplished. It will be readily seen that any type of conveyer which will do the work can be substituted for the4 IOO IIO

ciating such delint in the presence of additional cotton-seedto 4open up the mass and straighten the iibers and combine the longer fibers thereof with the linters of said seed.

2. The process herein described of treating the delint obtained from cotton-seed Jfrom which the linters have been removed which recess consists in introducing said delint into the presence of additional cotton-seed whereby the longer fibers of thel dehnt are caused to combine with the linters of the said cotton-seed. i

3. The process herein described of delinting eotton-seed which .consists essentially in removing and recovering the linters separate Y from the seed and its adhering remaining )fibers7 then removing the said fibers from said seed, and iinally recovering the remaining linters from the delint by opening up the mass of delint in the presence of additional `eotton-seed from which linters have not been removed whereby the extreme short fibers and foreign matter in the delint are permitted to escape and the longer :ibers of the delint are straightened out and combine with the linters ofthe said cotton-seed.

In testimony whereof l have signed my name to this speciication in the presence of two subscribing witnesses.
